Gender was also a deciding factor with 55 percent of men saying they would stop to help a female motorist while only 4 percent of women saying they would do the same for a lone male driver. Some of the male respondents said they would not be "comfortable" helping a lone female without someone else present, for fear that they would be perceived as a threat.

Just under 60 percent of respondents would help a stranded driver with young children in the car.

Sixty percent of drivers also said they would stop for an elderly motorist, with 71 percent of the male participants saying they would do so.
